Title: Method and apparatus for controlling the specific weight of a heat-treated liquid
IPC: A23C3/037
Filed: 1963-04-23
Abstract: 1,021,829. Indicating specific gravity. ALPURA A. G. April 23, 1963 [April 25, 1962], No. 16047/63. Heading G1S. [Also in Division A2] A method of maintaining a constant relationship between the final specific weight of a liquid and its initial specific weight in apparatus in which the liquid is heated by being directly brought together with steam and then cooled by expansion with some evaporation, involves either adjustment of the initial temperature of the liquid immediately before the liquid and steam are brought together or adjustment of the expansion temperature of the liquid, the control circuit for adjusting the particular temperature concerned being supplied with a desired value which is continuously adjusted in dependence upon variations of the other temperature. The sterilisation or pasteurisation of milk, fruit juices and pharmaceutical products are instanced. Thus, the expansion pressure of the liquid may be varied to adjust the expansion temperature or the initial temperature of the liquid may be regulated by varying the supply to a heat exchanger of vapour evolved during expansion and/or the supply of heating medium from an independent source. In the regulating system shown in Fig. 3, the measurement of the liquid preheat temperature by element 41 which is filled with a vapourisable liquid and produces inside the bellow capsule 43 a pressure corresponding to the temperature sensed, is transmitted by a rod 44 to a pivoted plate 45 which together with a nozzle 46 for compressed air controls the pressure in a pipe 47 in dependence upon the distance of the plate 45 from the nozzle aperture; the pressure in the pipe 47 is operative upon a diaphragm 49 of a servomotor 50 to control the valve rod 51 of a valve 25 for the control of heating medium to the heat exchanger 5. Changes in the temperature difference measured by the elements 41 and 42 are compensated by the horizontal movement of a rod 57 produced by vertical movement of a cam 56a.

Title: Apparatus for selecting tabulated documents
IPC: G06K19/00
Filed: 1945-06-25
Abstract: 622,819. Statistical apparatus. SAMAIN, J. June 25, 1945, No. 16129. [Class 106 (i)] [Also in Group XL (b)] Record cards, in which the recorded information appears as perforations y, Fig. 1, or other markings along a horizontal row, and in which a perforation x indicates whether the associated row bears a record, are sorted by passing under two cells, one affected by the perforation x and the other affected by the perforations y and associated with a selecting template apertured in accordance with the intelligence it is desired to select, both cells controlling a shutter for directing the cards to either of two bins. Cards from a hopper 1, Fig. 3, are fed by a reciprocating member 2 between rollers 4, 7, beneath a photo-electric cell, through feed rollers 8 and into bin 10s or 10r according to the position of the shutter 11. The perforation x produces a current in cell 16, Fig. 6, which is amplified at 25 and applied to grid of thyratron 27 whose output circuit includes relay 24, Fig. 3, controlling the deflector 11. Cell 17 is associated with a template 18 apertured reversely to the selection desired, so that cards showing the desired selection produce no current in the cell while other cards produce a current which is amplified at 26 and applied to the cathode of thyratron 27 to inhibit its discharge. To bring deflector 11 to the normal position after operation, the thyratron circuit is broken at 29a by a relay 29 operated by contact discs on shaft 33, Fig. 5 (not shown). The cell system may be multiplied to read several lines simultaneously, Fig. 7 (not shown), thus selecting cards bearing a combination of intelligences or cards bearing any one of several intelligences. Preferably, the intelligence is recorded by dividing the row into groups of six possible perforations, and making three perforations in each group. Where each row is divided into zones, each of which carries different recordings, cells 17 are provided for each zone. The system may also be adapted to select cards in which the desired information occurs in a particular row or rows, by inhibiting the actuation of relay 24 for other rows by a modification of the contact discs on shaft 33.
